speaking of wipers:

Anyone with a suggestion - I'm all ears. In my '89 Caprice, I've had constant issues with the derned wipers not 'parking' when they're supposed to (they just don't shut off sometimes) - usually, if I put it on 'delay' wipe, after the unit seems to get warmed up for a few minutes it'll shut them off.

Checked all the grounds - seem to be okay. Installed another wiper motor from a different car - I still have the same problem! ARgh! !

Could it be the silly-stick on the column that's bad ?? I'm at my wits end !

There is a circular plastic cam with a dip in it the parks the wipers once they are turned off. If the points in the relay that powers the motor when the cam goes to break the connection to the motor are burnt or pitted it will keep runing. Changing the motor should have "fixed" this problem unless you picked up one that has the same problem as yours did. You can disassemble one and see if you can file down the points to see if it fixes the problem, or at least watch rto see what it is doing.
